I started using Pinterest not long ago, and it's great for me. When I pin something to my board, I've got a visual reminder of what I marked. Like that a lot. When I want to go back to it, I just click on the image, and it takes me directly to the original source. When I re-pin someone else's pin, I do the same thing. I don't have any trouble getting to the original. You do need to make sure you're on the page for the post, not on the home page. (Pinning from the home page is bad pinning.) You can get a button right from pinterest. It's pretty easy. If you've got a site/blog where images are crucial, Pinterest is the place to be. Home design bloggers are getting lots of their traffic from it and the best ones are creating images to be pinned that helps users know the original source.
